This invention relates to pattern setting machines employed in winding yarns or threads of dilierent colors according to a pattern upon a loom spool preparatory to the use of such filled spools for weaving therefrom the desired Axminster carpets or rugs. In winding the yarn of different colors upon a loom spool it is customary to provide a plurality of non-driven rollers spaced circumferentially about the loom spool which contact the peripheral surfaces of the spool, and are rotated by said spool. The rollers comprise an upper roller and a pair of lower rollers, the said rollers being capable of being moved in opposite directions by the yarn being wound on the spool as the winding operationprogresses. The upper roller is connected to a suitable mechanism including a weighted member which enables the said roller to be moved upwardly to a limited degree, while the pair of lower rollers are also connected to a separate mechanism including a weighted member which permits these rollers to be moved downwardly Within certain limits. The separate mechanisms are designed to cause the rollers to exert a compressive force upon the peripheral surfaces of the spool, and also to counteract the force exerted upon the rollers by the yarn being wound upon the spool. With th setting frames embodying such mechanism the maximum length of each yarn or thread that it has been possible to wind on the spool is 28 feet.

, In the setting frame of the present invention a plurality of pressure applying members spaced circumferentially about the spool are provided which contact with the periph eral surfaces of the spooland exert a uniform compressive force upon the surfaces of said spool, such compressive force being maintained substantially uniform as the diameter of the spool increases as the winding operation progresses, The pressure applying members are arranged so that one of the members is above the spool and a pair of said members are beneath the spool. The operation of such pressure applying members is controlled by a single mechanism which causes the upper pressure applying member to exert a downward pull upon the loom spool and the pair of 1928. Serial in 267,684.

lower pressure applying members, an upward force against the loom spool. This mechanism also enables the upper pressure applying member and the pair of lower pressure applying members to be moved uniformly upwardly and downwardly respectively under the force exerted upon each of said pressure applying members by the yarn being wound upon the spool, and still maintain such members in peripheral contact with said spool during the entire winding operation. By this mechanism it is possible to wind to more yarn upon the spool than is possible with the setting frames as now proposed. With the old setting frames it is possible to wind on the spool yarns or threads of a length of only about 23 feet whereas the yarn spools which have been filled with yarn in the setting frame in accordance with this invention contain yarn the length of which is about 40 feet, the filled spool in both cases being of the same diameter.

Accordingly, one object of this invention is the production of a filled loom spool containing a greater length of threads or yarns than obtained with the prior practice, say for example, 40 feet.

Another object of this invention resides in the provision of amechanism for causing the pressure applying members to exert a substantially uniform force upon the peripheral surfaces of the loom spool throughout the entire winding operation.

Another object of this invention resides in the provision of a single mechanism which enables the upper pressure applying member and the pair of lower pressure applying members to be moved uniformly upwardly and downwardly respectively under the force exerted thereon by the yarn being wound upon the spool, and still maintain such members in peripheral contact with said spool during the entire winding operation.

A further object of this invention resides in the provision of amechanism for moving the upper pressure applying member out of contact'withthe loom spool and simultaneously causing the lower pair of pressure applying members to recede from said spool.

A further object of this invention resides in the provision of a mechanism for rotating the loom spool and stopping the rotation thereof after the spool has made a predetermined number of revolutions.

A still further object of this invention resides in the provision of a stop motion drive mechanism operable by one of the shafts for rotating the loom spool.

A still further object of this invention resides in the provision of a pair of shafts provided with clutching members, and a loom spool having flanged ends adapted to interfit said clutching members.

Still another object of this invention resides in the provision of a mechanism for latching and unlatching the spool when in clutching engagement with the rotatable shafts.

Further objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawings, in which,

Referring to the drawings. the illustrative machine shown therein as embodying the invention comprises side frames 1, 1, the tops of which are so constructed as to form supports in which the shafts 5 and 6 are mounted for driving the spool 7 preferably made of metal. The ends of the spool 7 are provided with en ped ends 8 and 9, preferably made of meta having projections or lugs 10 and 1h the lug 10 being diametrically opposite to the lug 11. One end of each of the shafts 5 and 6 is provided with a disk 12 and 13 respectively. Each of the disks 12 and 13 is provided with a cross-wise slot 14, the said slots being adapted to receive the lugs 10 and 1.1 of the cupped ends 8 and 9, and clutch the cupped ends 8 and 9 to the shafts 5 and 6,

so that rotation of the shafts is transmitted to the spool.

Shaft 6 is driven by the gear 16 fast thereon, said gear in turn being driven by a larger gear 17 mounted upon a shaft 18. Gear 17 is driven by a pinion 19 mounted upon a shaft 20. The shaft is in turn driven by the large sprocket wheel 21 through the medium of the chain 22 and sprocket 23 carried by the shaft Tl e shaft 21 is in turn driven by clutch disk mounted thereon engaging the clutch member 26 carried by the shaft 27. Motion is imparted to shaft 27 through. the medium of gear 28 mounted thereon being in operative engagement with gear 29 carried by the motor shaft 30 of the motor 31.

Upon the shaft is mounted a gear 115 which meshes with a larger gear 116 carried by a shaft 117. The gear 116 meshes with a pinion 118 carried by the shaft 20. Motion is imparted to the shaft 20 from the motor shaft 30 of the motor 31 through the medium of the mechanism above described in con-, nection with the shaft 6.

It will be apparent from the mechanism thus described that when the clutch disk is in clutching engagement with the clutch member 26 motion will be imparted to the shaft 20 from the drive shaft 27, which shaft 20 will in turn drive the train of gears, and thus rotate the shafts 5 and 6 and the spool 7.

The driven clutch disk 25 is adapted to be clutched t0 and unclutehed from the drive clutch member 26 carried by the shaft 27 by the following mechanism. The driven clutch disk 25 carries a collar 32 having pins 34: which are embraced by the yoke The yoke 35 is pivotally mounted on the shaft 36 supported in the brackets 37 carried by the side frame 1 of the machine. Pivotally mount-ed upon the shaft 36 is one end of a lever 39, the other end of which is providcz with a longitudinally recessed portion -16 embracing the pin &1 carried by one end of the bell crank lever 42 pivotally mounted on the pin 43 supported in a bracket 38 secured to the side piece 1 of the machine. The bell crank lever 42 is in turn connected to the rod 45 having a threaded end 46, by the pin 41 1-. Secured to the crank lever 12 and the side frame 1 is a spring 47, such spring being provided for holdingthe driven clutch disk 25 in inoperative position.

The threaded end 4.6 of the rod 4E5 extends through the guide 48 and is adjustably secured thereto through the medium of the nuts 49 and 50. The guide 18 is pivotally connected to the bell crank lever 53 as at 52. The bell crank lever 53 is pivotally secured to the side frame 1 of the machine as at 54. The other end of the bell crank 53 is secured to the pin 56 which pin also has secured thereto one end of the lever 57. The opposite end of the lever 57 is connected by the pin 58 to one and 170.

' shaft 128 also mounted in bracket 229.

end of the treadle lever 59 which is secured to one end of a rock shaft 61 carried in brackets 60 secured to the side frame 1. The treadle lever 59 is provided with a treadle 3.

It will be observed that the mechanism thus described will cause the clutching of the driven clutch disk 25 to the drive clutch member 26 by the operator placing his foot upon the treadle 3, and depressing such treadle. In order to retain the driven clutch disk 25 in clutching engagement with the drive clutch member 26, a latching device is provided. Such latching device comprises a latch memher 160 which is fulcrumed as at 162 in a bracket 161 secured to the side frame 1. One end of the latch member 160 is providedwith a cut out or notched portion 163 which is adapted to engage the squared end 163 of the bell crank 53. The latch member 160 is connected to an arm 164 fixedly secured to a shaft 166 supported in brackets 165 by a rod 167. The end of rod 167 which is secured to the arm 164 is threaded and is adjustably secured to the guide 168 through the medium of nuts 169 The guide 168 is provided with a boss 171 having an opening therethrough for the reception of the pin 172 which connects the arm 16 1 to the guide 169. The arm 16% is provided with spaced openings 173 for lengthening or shortening the throw of said arm. Fixedly mounted upon the shaft 166 is a hand lever 174; which is connected to one end of a rocking arm 137 pivotally mounted upon a pin 135 by a cord or chain 139, (Fig, 3).

. Mounted upon the pin 135 and secured thereto 1s a lever 132 having at one end thereof a lug 131 which is adapted to ride upon the periphery of a stop motion disk 129 and to seat in the notch 130 therein to stop the rotation of the spool shafts 5 and 6. A weight 136 is secured to the oppositeend of the lever 132 by means of a link 1333.

A stop motion drive mechanism is also provided for stopping the rotation of the spool shafts 5 and 6, after they have made a predetermined number of revolutions. This stop drive mechanism comprises a worm 123 journaled upon the outer end of shaft 5 which meshes with a worm gear 12a carried by a shaft 125. Mounted upon the shaft 125 is a gear 126 which meshes with a gear 226 carried by a shaft 227 mounted in the longitudinal slots 223 of the bracket 229. The gear 226 meshes with a larger gear 127 carried by a Journaled upon the shaft 128 and mounted thereon so as to rotate with the gear 127 is a stop motion disk 129 provided with a notch 130. The lug 131 of the lever 132 is adapted to ride about the periphery of the stop motion disk 129 and seat in the notch 130 under the influence of weight 136 to stop the machine as pointed out above. The ratio of gears 126, 226, and 127 may be changed so as to vary the speed of the stop motion disk 129. Such mechanism is particularly advantageous in that it determlnes the time interval within which the spool 7 is permitted to rotate without varying or changing the speed of the rotation of the spool shafts 5 and 6. The ratio of the gears 126, 226 and 127 is so fixed that by the time the lug 131 has traversed the entire periphery of the disk 129 and has entered into the notch 130 the winding of the yarn upon the spool 7 is completed.

The seating of the lug 131 in the notch 130 of the stop motion disk 129 causes the pin 135 to rotate and in turn actuate the rocking arm 137, the movement of said arm exerting a pull upon the hand lever 17 1 through the cord 139. This pull upon the hand lever 174 is in turn transmitted to the arm 164 and rod 167 carrying the latch member 160 to move the notched portion 163 of said latch member out of engagement with the squared end 163 of the bell crank lever 53, and thereby permit the driven clutch disk to disengage from the driven clutch member 26 and return to inoperative position under the action of the spring 17.

It is to be noted that the hand lever 17% is provided to permit the operator to stop the machine at any time during the winding operation, and also to enable the operator to release the lug 131 from the notch 130 of the stop motion disk 129.

In order that the threads may be wound tightly upon the spool this invention provides an upper pressure applying member or roller 80 and a pair of lower pressure applying members or rollers 81 and 82 which extend parallel to the spool 7 and which are yieldingly supported in a manner to exert pressure against the threads being wound upon the spool as the body of threads being wound thereon increases in diameter.

The upper pressure roller 80 has its ends j ournaled in a pair of arms 103, one end of which is provided with a. notched portion 104:.

Depending from the arms 103 are extensions 105 provided with arcuate slots 106 which embrace pins 107 carried by the levers 108 mounted upon a rock shaft 109. The other end of the levers 108 are secured to the arms 103 as at 66. The mechanism for operating the rock shaft 109 in order to move the upper pressure roller 80 from the position shown in Fig. to the position shown in Fig. 6 will be hereinafter described.

The arcuate slots 106 are provided for the purpose of permitting the arms 103 supporting the pressure roller to be moved upwardly about the point 66 as a pivot as the diameter of the yarn being wound upon the spool 7 increases. Such slots also act to limit or restrict the downward movement of the arms 103 supporting the pressure roller when said roller m moved away from the spool or to the position shown in Fig. 6.

The ends of the levers 71 adjacentthe shaft 64 are connected together by means of The opposite ends of the levers 71 are connected together by a bar 76 upon which are mounted a plurality of weigl'its 77 interposed between weights 78 and 79.

Thelower pressure rollers 81 and 82 have their endsjournaled in the upper ends of rods 90 ands91. The rods 90 and 91 extend through guides 92 and-93 attached to the inside faces of the side plates 1. The lower ends of the rods 90 and 91 are threaded and are adjustably secured int-he casting 96 by means of nuts 97, and 98. ;The casting 96 has a bossor projection 62 which is connected to the shaft 95 by means of a'link The mounting of; the upperpressure roller and the pairof lower pressure rollers 81 and 82 with respect to the spool 7 is such that the pointabout which the upper pressureroller 80 rotates when in operative enagement with the spool 7 is not equidistant gromthe respective points about which the pair 0ft lower pressure rollers 81 and'82 rotate Such mounting of the upper pressure roller 80 is highlyimportant as it results in the peripheral surface of the upper pressure roller 80 engaging the yarn being fedto the spool at a-point below the upper peripheral surface of the spool mounted .in the machine prior to the winding of the'yarn thereon, and

thereby causes the yarn to be uniformly wound 1 upon the spool.

It isto be noted that the shaft 64 acts s the fulcrum for the levers 71, and that the levers 1110 controlling the upper pressure levers 71 at a point between the fulcrum or shaft 64 and the weights'77, 78 andc79 sup ported by the ends of the levers-71 while the ,rods and 91 are connectedto-the levers 71 on the opposite side of the fulcrum or shaft 64.

exert. a substantially constant pressure upon the spool 7 as the levers 71 move from the full line position shown in Fig. 4 to the dotted line position shownvin such figure as .the

diameter of the yarn being wound on the spool increases.

It will be apparent from the mechanism thus described that the upper pressure-roller 80 is yieldably supported with respect to the spool 7 and as the thread being wound thereon increases in diameter it is capable of being moved by the force exerted thereon by the body of the threads being wound on the spool, and still be maintained in intimate con tact with the spool 7 through the action of the weights 77, 78, and 79exerted through the levers 71 and lever 110,,and rods 90 and 9].

The pair of lower pressure rollers 81 and 82 are also capable of being moved by the bodyof thrcadsbeing wound on the spool, and yet be retained in intimate contact with the spool 7 through the action of the weights 77, 78 and 79 exerted through link 63, cast- In the form shown in Fig. 11, the upper pressure roller 80 In the form shown in Fig. 12, the lower pressure rollers 81 and are replaced by plates 221 and 224.

After the wlnding of the yarn upon the spool 7 has been completed the upper pressure .roller 80 is moved away from the spool 7, the

position shown in Fig. 4 to the position shown inFig. 6 bya novel mechanism which will'now be described. Such mechanism also includes means for simultaneously lowering the'pair of lower pressure rollers 81 and 82.

As described above the arms 103 in-which are journaled the ends of the upper pressure roller 80 are pivoted to the lovers 108 as at 66, which levers are in turn mounted upon the rock shaft 109. Carried by the rock shaft 109 is an arm 140 which in turn is connected to a rod 141 as at 142. The rod 141 is adjustably connected to arguide 143 which guide is in turn connected to the arm 144 pivotally supported in a bracket 146 secured to the frame piece 1 of the machine by means of a pin 145. To the pin 145 is secured one end of chain 147 which rides over an idler roller 148 supported in a bracket 149 and carries a weight 150. Secured to and carried by the arm 144 is an idler roller 151 which rides in the slot 152 of the cam 153 mounted on a shaft 154.

As pointed out above the levers 110 having their upper ends turned inwardly sons to form detents or hooks 111 which detents or hooks engage the notched portions 104 of the arms 103 are supported in connectors 112. The connectors 112 are in turn adjustably secured to levers 71 by pins 68 held in slots 69 The levers v71 are also provided with slots 73 in which are supported rollers 74 adapted to ride upon theperiphery of cams 75 by the shaft 154 Mounted upon the cam shaft 154 is a sprocket wheel 183 which is connected to a sprocket 186 mounted upon a stub shaft 185 supported in a bracket 189 of the side frame 1 by means of sprocket chain 184. Carried by the stub shaft 185 is a gear wheel 181 which meshes with a gear 180 mounted upon a stub shaft 187 supported in a bracket 188 secured to the side frame 1. Keyed upon the outer end of the stub shaft 187 is a crank handle 182.

By the operator turning the "crank handle 182 motion is imparted to the camshaft 154 through the gears 180, 181, sprocket whee] 186, sprocket chain 184, and sprocket wheel 183. The rotation of the cam shaft 154 causes the rollers 74 supported in the longitudinal slots 73 of the levers 71 to ride about the periphery of the cams 75 carried by said shaft 154. The riding of the rollers 74 upon the periphery of the cams 7 5 causes the weighted lever 71 to be raised thus lowering the pair of lower pressurerollers 81 and 82.

The rotation of the cam shaft 154 also causes the roller 151 carried by the arm 144 to I. ride in the slot 152 of the cam 153. The riding of the roller 151 in the slot 152 of the cam 153 exerts a pull upon the rod 141 which is transmitted in turn to arm 140 and rock shaft 109 to rock the said shaft and thus move the upper pressure roller 80 to the position shown in Fig. 6.

In order to restore the upper pressure roller 80 and pair of lower pressure rollers 81 and82 to the position shown in Fig. 4, the. operator turns the crank handle in the reverse direction.

The mechanism for releasably latching the spool 7 upon the shafts 5 and 6 will now be described. Such mechanism comprises a bracket 190 secured to the side plate 1 of the machine to which is pivotally secured a lever 192 as at 191. The lever 192 is provided with a circular opening which receives the collar 242 fixedly secured to the reduced portion 241 of the spindle shaft 6 through the medium of set screws 243. The other end of the lever 192 is provided with a slot or opening 194 in which is supported one end of a hand rod 195. The other end of the hand rod 195 is supported in a standard 196 secured to the opposite side plate 1 of the machine. The end of the hand rod 195 which is supported within the opening 194 of the lever 192 is tapered and is provided with a projection 197 whlch 1s adapted to bear against the exterior surface from the shafts 5 and 6, the operator places his hand upon the hand rod 195, pushes the said rod upwardly until the projection 197 is moved out of engagement with the exterior surface of the lever 192 when the end of the hand rod 195 will be pulled through the opening 194 by the action of the spring 199. The operator then pulls the lever 192 in an outwardly direction thereby causing the slotted disk 13 of the shaft 6 to be moved out of engagement with the projections 10 and 11 carried by the cupped end 9 of the spool 7. The operator then. lifts the end of the spool 7 which has been freed from engagement with the shaft 6 and pulls the spool outwardly so as to de-clutch the cupped ends 8 from the slotted disk 12 of the shaft 5.

It will be obvious that many changes and alterations may be made in the structure above described without departing from the spirit of this invention, and such modifications are within the intent of the appended claims.
